VS 2008 - Calculate Factorial From Number And Display In Textbox

Sep 14, 2009

So I need to get a button to take the number that a user enters into a textbox, calculate the factorial from that number, and display it in another textbox. I can't seem to get this to come out right.

Here's some of the code I've been playing with.
Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
Function Factorial(ByVal txtFactorial As Decimal) As Decimal
If txtFactorial <= 1 Then
MessageBox.Show("Enter a number greater than 1")
Else
txtAnswer = Factorial(txtfactorial - 1)
End If
End Function

Now I have to just work out the code part. Can a function be under a button? I'm getting an error about that. I'm also getting an error about the txtAnswer=Factorial(txtfactorial-1) part of the code.

They both output the repsective amounts perfectly. I need to do a calculation on them, by subtracting PartialSettlementAmountRecd from TotalClaimed. I have tried the following, but it just outputs a random number, not the amount I require.

Progress Bar With Calculation?

Aug 25, 2011

I have an array of characters. Depending on the number selected (between 1 and 30), the program selects random characters and concatonates them into a string. Kind of like how I think a password generator would work.I want to update a progress bar to show how the operation is going, but I need to reserve 20% of the progress bar for some actions before this, and the last 10% for the actions that follow it. So there is 70% available to use. My question is:If I set the progress bar to 20% and do the following math: 70/NumOfChars, then use a for loop to add the result of this to the progress bar (pb+=result), why does the total progress NOT EQUAL 90%!

Using Functions To Run Calculation?

Sep 11, 2011

I'm trying to work on code where I enter number of hours into a textbox (txtHours) and then EITHER you press a button (cmdPay) and then the income for the week is calculated and shows up in a second text box (txtPay) OR txtPay does the calculation itself, everytime a number is typed into txtHours.

Currently, my code is trying to do the former, because I have NO idea how to even approach the second option.My problem I am having with my code, is I don't know how to properly dim my parameters, since my "button_click" code keeps coming up with this error:Argument not specified for parameter...

Public Function PayTotal(ByVal cnthours As Double, ByVal standpay As Double, ByVal overpay As Double) As Double

Apply Calculation To A 2d Array?

Mar 23, 2012

I have a 2d array and I want to do a calculation on each element in the array and then return the index which results in the smallest value.

I have tried iterating through each element in the 2d array and running the calculation. If the calculated result is smaller than the currently stored minimum I set that to the minimum.

This works but it runs so slowly it makes the solution a non starter. It performs each calculation quickly but because of the number of elements in the array the calculation for the whole array is stupidly long.

Array Calculation With CSV File?

Dec 4, 2011

I am trying to work with taking in and parsing CSV files. Right now I have it taking in and producing something like this:

The program loads the csv and copies the data into an array as such:

ReDim strarray(num_rows, num_cols)
For x = 0 To num_rows
strline = strlines(x).Split(",")

[Code]....

etc. I guess my main problem is trying to perform calculations to all values in a specific column. To start I am just trying to figure out how to isolate the columns and found that by using MsgBox(strarray(x, num_cols)) it will msgbox everything in the second column twice. I just want to try and understand how I can perform a basic calculation like multiply every value in the first column by 2 and every value in the second column one by 3.

Calculation In Textbox - X Value For Column And Y For Row

Jun 12, 2009

In my form I have a text box for user to enter the number of column and row. And I also have a text box to enter the first X value and Y value. Now what I want to do is if user enter 2 for row and 10 for column then now I will have two rows with 10 column. The X value is for column and Y value is for row.

It will look like this
**********
**********

When the user enter the first X and Y value. For next X and Y value i must plus the original value with 2.54.
So my X1=TextBox1.Text
Y1=TextBox2.text
this values are input by user.

So
X2=TextBox1.text + 2.54
X3=X2 + 2.54.
and so onn. Same apply for Y
Let say user input are X=100 and Y=100
The value for first * is X= 100 and Y=100
Second *X=102.54 and Y= 100............. and so on
For 11th * X=10th *value + 2.54 Y= 100+2.54 and so on
The row and column is not same always it depends on user..
